Joint is the key to ensure the safe and stable operation of space manipulator as one of the critical components.For the characteristic of a high failure probability of the drive motor,the fault-tolerant joint is designed against a single motor failure and the detail dynamic model is established...
The overall model performance is evaluated using the Kling-Gupta Efficiency, while the model’s ability to represent the low-flow periods is evaluated using the Log-Nash Efficiency at a sub-catchment scale. The change in reservoir outflows using the original GWAVA equation and the new modified ...

1) Large scale ballistic vehicle 大型弹道式飞行器2) Ballistic vehicle 弹道式飞行器 1. Based on rocket-boost launching mode,the analytical expressions between takeoff mass and range as well as propellant specific impulse and payload were deduced for three kinds of hypersonic vehicles,including ...
on at least 3 spacecraft that I know of. Some of the more exciting projects I have worked on are not shareable. I am also am FAA certified glider pilot and FAI certified gold glider pilot. I fly both full scale and model sailplanes. I am Microsoft certified and ComTIA A+ certified....
Silica aerogels, a porous bulk material made up of nanometer-scale silica chain networks, are also uniquely lightweight and superb thermal insulators. The porosity of these materials exceeds 98.5% and their thermal conductivity is as low as 0.25 Wm−1 K−18,9,10. A number of industrial ...
With a large-scale survey completed during the early stages of Italy's lockdown, we studied the appreciation (funniness and aversiveness) of different formats of Covid-19 humor shared on social media. Results of an analysis of the role of demographic, personality, and psychological distance ...
The interannual variability of precipitations in our study area (18°–40°S) is determined by large-scale modes such as the El Niño-Southern Oscillation (ENSO) and the Southern Annular Mode (SAM). The ENSO warm phase (El Niño) is associated with positive sea surface temperature (SST)...
